我国某出口公司G收到国外来证，其中在“DOCUMENT REOIRED”中要求如下：
“BENEFICIARY'S SIGNED DECLARATION STAING THAT：1/3 0RIGINAL MARINE B/L AND ONE SIGNED ORIGINAL OF EACH OTHER DOCUMENT PRlFSENTED AT THE BANK WERE SENT DIRECTLY TO BLL HAIFA BY SPECIAL COURIER(IF SHIPMENT EFFECTED BY SEA)OR PHOTOCOPY OF ORIGrNAL CERTIFICATE OF ORIGIN AND ONE SIGNED ORIGINAL OF EACH DOCUMENT PRESENTED AT THE BANK WAS ATTACHED TO ATD ACCOMPANYING THE GOODS(IF SHIPMENT EFFECTED BY AIR)”(受益人签署的声明书，证明1/3正本提单和其他正本单据通过特别快件直接寄给BLLHAIFA(如果是通过海运)或原产地证书的副本和其他正本单据己随货物(若通过空运))。G公司将全套单据(3份)正本提单及所要求的发票，装箱单及其他REOUIREDDOCUMENTS交给中国深圳通知行，后经中行复审无异后，然后交全套单据寄往国外开证银行承兑。中行于到期日收到开证行通知：“因所交单据与信用证要求不符，拒付货款不符之处为：信用证在所需单据第(7)款中要求，若为海运，1/3的正本单据需用特快专递直接寄往BLL HAIFA．”因此，G公司立即与客户联系，说明由于工作疏忽没有按信用证要求办理，请其尽快付款赎单。不久客户办理了付款赎单，终于顺利解决了此案。请问在此案中我们应注意什么?
